Hi!
I experience this bug today as well. Attached is a Pd-patch that simulates this crash caused by the message TouchOSC is sending if page is turned (although this can be changed in the TouchOSC editor!).
This is the gdb output:
Program received signal EXC_BAD_ACCESS, Could not access memory. Reason: KERN_PROTECTION_FAILURE at address: 0x00000000 0x045f1c59 in routeOSC_list (x=0x5e5990, s=0x0, argc=0, argv=0x0) at routeOSC.c:410 410 if (argv[0].a_type == A_SYMBOL) routeOSC_doanything(x, argv[0].a_w.w_symbol, argc-1, &argv[1]);
I attached an easy fix for routeOSC.c
So either rebuild routeOSC with the fix or change the message TouchOSC is sending on page turn. (This is done by deactivating the auto checkbox below Page, Name and OSC)

It sounds like you have two issues: one is that the new external crashes Pd as soon as it is instantiated, the other is that some OSC messages do the same thing when [routeOSC] is involved. For the second thing, just use [udpreceive] | [unpackOSC] | [print] and switch pages to see what raw message is being sent. For the first thing, make a new patch and put a [routeOSC] in it and see what the console prints. But then again you don't seem to be able to start Pd at all from the console. Is that correct?

Thanks, Martin. I compiled it and test it. Again, in UbuntuStudio 12.04.3, it makes PureData crash. There's no message, it just crashs.
Is anything I could do to help to avoid that? How could I debug it?
In the other hand, I'm having troubles to launch Pd from console (to see if any message is there)... it can't open my patch. So, I'm writting another mail to list.

From trunk/externals type make mrpeach or make mrpeach_install (which doesn't actually install the files, it puts them in externals/build/lib/pd-extended/extra) Martin Thank you. 2013/9/15 Martin Peach <martin.peach@sympatico.ca <mailto:martin.peach@sympatico.ca> <mailto:martin.peach@sympatico.ca <mailto:martin.peach@sympatico.ca>>> On 2013-09-14 19:28, Mario Mey wrote: Martin Peach, I read somewhere that changing pages in TouchOSC makes Pd (or Pd-Ext) to crash. My Pd-Extended doesn't crash, but this error is shown: "* routeOSC: ignoring empty listÂ…". That doesn't happen here. There is no such message in the source code. Maybe you have an older version of routeOSC? The OSC specification allows empty messages, and [routeOSC] should output a bang if it routes such a message. Older versions of [routeOSC](before March 2012) didn't work properly, so you probably just need to find a more recent one or build it from svn.

Martin Today, I've installed Ubuntu Studio 12.04.3 (with lowlatency kernel). It seemed that it was a good distro for my use... but switching pages DOES make Pd-Extended to crash. I reported-suggested this in this thread: http://hexler.net/forum/__viewthread/992/
http://hexler.net/forum/viewthread/992/, where I wrote some
other info, maybe usefull. The config where it doesn't crash: /Ubuntu 12.04, Kernel 3.2.0-49-generic, Pd-Extended 0.43.4 (download from PPA as the Pure Data page says), jackdmp
1.9.8...// / The other config:
/Ubuntu Studio 12.04.3, Kernel 3.2.0-51-lowlatency, same Pd-Extended version, Jack that came with UbuntuStudio (don't know wich version)/ Any other information that could be useful to fix this? Like I wrote in the thread, I suggested TouchOSC that it should send non-empty lists. But, TouchOSC is closed-code... so, there's no easy feedback.
